DIN 610 Fitted Tie Bolt

The DIN 610 fitted tie bolt can be purchased from the available range or ordered in missing sizes. The fastener consists of three parts:

• a hexagon head sized for standard wrenches;
• a smooth section of the working shank;
• a short spigot with M8–M36 metric thread.

The threaded part of the shank is smaller in diameter than the solid section, which increases the strength of the fastener joint several times over. This is also aided by the high precision of hole preparation — hence the word “fitted” in the bolt’s designation. During installation, it must fit tightly into the bore. Despite the hexagon head for a wrench, the DIN 610 bolt is additionally supplied with a nut and washer of the corresponding size.

The bolts are made from steel alloy of property class 5.6 and 8.8. Stainless steel grades A2 and A4 are also used. The fastener’s application area includes mechanical engineering, instrument making, and other industries.
